MS micing cord question

I am new to MS micing and want to try it. I understand you need to use a figure 8 mic and make a cord where one input is out of phase with the other.

For the M mic, I will run it through a single channel John Hardy pre. I will be using the figure 8 mic with a 1402 VLZ-pro Mackie board where all the inputs are controlled by one phantom power switch. In other words, all inputs get phantom power or none of them do.

My question: Will the phantom power do anything to the mic if it goes into the mic through both cords? If so, how do I record to keep this from happening, and still have the M mic run through the Hardy?
